1st round Flex/WR2 help PPR

Need help deciding my Flex and WR2. Candidates are:

Josh Gordon
Courtland Sutton
Corey Davis

Kerryon Johnson (listed Q but doubt he plays)
Marlon Mack

Starting Mark Ingram and Spencer Ware at RB, Keenan Allen at WR

I think you have to go Sutton here. as a WR 2, and I would play josh Gordon I dont think Corey Davis is going to do much tonight.
